The Laboratory Controller Module includes a
microprocessor-based assembly with on-board
differential pressure transducers for airflow
measurement. Wiring termination for input and output
points, FLN communications, and power are provided
via removable terminal block connections. The room
temperature sensor is connected to an on board RJ-11
jack.
The controller connects to the following external
devices:
• Fume Hood Controller
• Fume Hood Flow Module
• Lab Electronic Damper Actuator Assemblies
• Electronic Hot Water Valve
• Room Temperature Sensor
• Portable Operators Terminal
• APOGEE Automation System
• Digital Input Devices (e.g., wall switches)
• Digital Output Devices (e.g., alarm horn)
• Laboratory Room Air Terminals boxes

Laboratory Room Controller Flow
Measurement
Laboratory Room Controller airflow measurement
consists of the controller module A/D conversion
circuitry, on-board differential pressure transducers (2)
and auto-zero modules (2). Air velocity sensors (within
the air terminal) send the velocity signal to the LRC
differential pressure transmitter. Auto-zero modules
are connected to the air velocity pressure transducer's
inlet ports to enable automatic periodic re-calibration.
This re-calibration ensures accurate, drift-free and
stable airflow measurement. Automatic re-calibration
of the differential pressure transducers occurs upon
system power-up and when airflows are stable.
